Water Quality Monitoring For Selected Priority Watersheds In Arkansas, Upper Saline, Poteau And Strawberry Rivers, L. B. Massey, J.A. Mccarty, M.D. Matlock, A.N. Sharpley, B.E. Haggard

Technical Reports

Arkansas Natural Resources Commission has identified three priority hydrological unit code (HUC) 8 watersheds, the Upper Saline (HUC 08040203), Poteau (HUC 11110105), and Strawberry Watersheds (HUC 11010012). SWAT models have been developed to estimate nutrient and sediment loads in these watersheds where limited water‐quality data was available. The purpose of this project was to collect additional water samples across these HUC 8 watersheds to better understand how water quality changes across subwatershed with differing land use mixes, as well as estimate nitrate‐nitrogen (NO3‐N), total phosphorus (TP), and total suspended sediment (TSS) loads. Water samples were collected at twenty sites near …

Addressing Trans-Boundary Challenges Through Collaboration: How Organizations "Harmonize" Actions And Decisions Across Problem Landscapes, Rachel Fleishman

Dissertations - ALL

Collaborative governance- or collaboration- has become increasingly important for the design and implementation of public policy in the United States. This dissertation explores concrete and unique policy-related benefits emerging from collaboration, and the processes by which they emerge.

Collaboration is defined broadly as "any interaction between two or more organizations undertaken with the intention to cooperate." This definition is applied in the context of water quality management, where the physical nature of watersheds and the lack of regulatory authority available to policy-makers leads to a variety of collaborative arrangements.

A survey of literatures addressing collaboration from different theoretical angles revealed …

Ecohydrologic Impacts Of Climate And Land Use Changes On Watershed Systems: A Multi-Scale Assessment For Policy, Paul A. Ekness

Open Access Dissertations

Maintaining flows and quality of water resources is critical to support ecosystem services and consumptive needs. Understanding impacts of changes in climate and land use on ecohydrologic processes in a watershed is vital to sustaining water resources for multiple uses. This study completes a continental and regional scale assessment using statistical and simulation modeling to investigate ecohydrologic impacts within watershed systems.

Watersheds across the continental United States have diverse hydrogeomorphic characters, mean temperatures, soil moistures, precipitation and evaporation patterns that influence runoff processes. Changes in climate affect runoff by impacting available soil moisture, evaporation, precipitation and vegetative patterns. A one …

An Addendum To Segment Analysis Of Sucker Brook: The Location Of Sources Of Pollution, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

This supplemental report is an addendum to the original study 'Segment Analysis of Sucker Brook: The location of sources of pollution' (Makarewicz et a/. 1999). In the original study, recommendations for further investigation of two segments of Sucker Brook were suggested as follows. 1. The segment above Site 7 (Figure 1) in the City of Canandaigua had high concentrations of soluble reactive phosphorus (SRP) and total phosphorus (TP) during an event January 1999. The source(s) was not identified. 2. The segment between Sites3 and 4 (Figure 1) had high concentrations of soluble reactive phosphorus (SRP), total phosphorus (TP) and total …

Final Data Report: Sodus Bay Limnology, Lake Chemistry, Phytoplankton And Zooplankton Abundance And Nutrient And Soil Losses From The Watershed, 2004, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

During the spring, summer and fall of 2004, limnological and sub-watershed data were collected from Sodus Bay. In general, monitoring and analysis were designed to meet the following objectives: document current lake, sediment and nutrient conditions; document stream loading to the lake; characterize the bay's community of phytoplankton and zooplankton to provide a benchmark against which the effectiveness of future management actions can be measured. This program will assist in developing a watershed enhancement plan and provide data for a simulation to determine the need for and likely success of adding alum to decrease phosphorus loss from the anoxic hypolimnion.

The Sucker Brook Watershed Revisited, Joseph C. Makarewicz, Theodore W. Lewis

Joseph C Makarewicz

Mitigation of soil and nutrient loss from the landscape continues to be a concern within watersheds of the United States and indeed worldwide. There are a number of reasons for this concern. Depletion of agricultural soil is counterproductive to good farming practices and crop productivity. Suburban, urban, and agricultural runoff and concomitant nutrient and soil loss to downstream aquatic ecosystems may produce undesirable effects including increased numbers of bacteria, algae, and macrophytes, increased siltation, and decreased aesthetics – in general, a deterioration in both surface (streams) and groundwater quality downstream resulting in cultural eutrophication of lakes and streams. In central …

The Development Of An Stream Water Quality Assessment Index To Evaluate Stream Health Conesus Lake Tributaries Spring 2011, Joseph Makarewicz, Theodore Lewis, Blake Snyder

Joseph C Makarewicz

The major goal was to develop an assessment tool for watershed health utilizing the USDA data base. Such a tool would allow the county to evaluate the status of watersheds; that is, are they improving, getting worse, or not changing. An evaluation tool of this type would allow further development and direction of the Conesus Lake Watershed Management Plan.

Monitoring of two of the USDA streams (Cottonwood Gully and North McMillan Creek) was changed to the spring rather than the summer. This was done as a result of last year’s work which suggested that spring monitoring may provide a better …

Nutrient And Sediment Loss From The Watersheds Of Canandaigua Lake, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

In the past three years of tributary monitoring, we have established the importance of meteorological events to the loss of nutrients and material into Canandaigua Lake. We have also prioritized the sub-watershed in terms of those losses and narrowed the focus of remedial attention down from sixteen to six sub-watersheds. This has allowed a shift in a portion of the monitoring towards the identification of the actual sources, both point and non-point, of pollution in the priority watersheds. The Sucker Brook Segment Analysis has been completed (Makarewicz, Lewis and Lewandowski 1999). Intensive monitoring is also continuing in the watershed. At …

Stressed Stream Analysis Of Deep Run And Gage Gully In The Canandaigua Lake Watershed, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

Deep Run and Gage Gully subwatersheds are located at Canandaigua Lake’s northeast corner. Both subwatersheds are relatively small in size but a three-year monitoring program has identified them as contributing disproportionately high loads of nutrients and suspended solids (soils) to Canandaigua Lake. Within the entire Canandaigua Lake watershed, Deep Run lost the most phosphorus and nitrate per unit area of watershed to Canandaigua Lake (January 1997 to January 2000), while Gage Gully ranked third. Also, the Deep Run and Gage Gully subwatersheds ranked 3rd and 5th for total Kjeldahl nitrogen (TKN) loss and 2nd and 3rd for total suspended solids …

Segment Analysis Of Sucker Brook: The Location Of Sources Of Pollution, Joseph Makarewicz, Theodore Lewis, Stephen Lewandowski

Joseph C Makarewicz

Sucker Brook is located in the northwest portion of the Canandaigua Lake watershed, Ontario County, New York (Figs. 1 and 2). The relatively large watershed encompasses 6.9 square miles and flows into Canandaigua Lake at the City of Canandaigua. The Canandaigua Lake Watershed Task Force with the assistance of the Ontario County Planning Department and the Soil and Water Conservation District has monitored Sucker Brook since 1996 in collaboration with the State University of New York at Brockport's Center for Applied Aquatic Science and Aquaculture (CAASA). Monitoring efforts have included the installation of a permanent gauging and sampling station located …

Analysis Of The Existing Water Quality Database For The Sandy Creek And South Sandy Creek Watersheds – 1997 To 2005, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

Runoff from agricultural lands containing soil and nutrients poses a known threat to the water quality of embayments and coastal regions of Lake Ontario (Makarewicz 2000). The Lakeview Marsh State Wildlife Management Area in Jefferson County, NY is a prime example of these types of ecologically valuable coastal wetland and embayment habitats. This embayment / wetland complex is fed by the watersheds of Sandy Creek and South Sandy Creek. The mouths of these creeks contain globally rare freshwater dunes, diverse wetlands and several types of globally rare vegetation. Sandy Creek also provides an emergency unfiltered drinking water supply for the …

Small Intermittent Rivulets Versus Major Tributaries: The Loss Of Soil And Nutrients From Selected Small Subwatersheds Compared To The Major Subwatersheds Of Canandaigua Lake, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

The rivulets that drain small subwatersheds of Canandaigua Lake contributed significant amounts of total Kjeldahl nitrogen, nitrate, soil and phosphorus to Canandaigua Lake. The large amount of material being lost from these small subwatersheds was surprising when compared to larger nearby watersheds despite the fact that only two events were sampled. This pilot study shows the potential importance that small intermittent streams may have on the health of Canandaigua Lake. We recommend that the watersheds studied be further interrogated as to potential land-use practices that could be the cause for the high losses observed. A further, more intensive study, looking …

A Spatially Explicit Watershed Scale Optimization Of Cellulosic Biofuels Production, Jingyu Song

Open Access Theses

Producing biofuels from energy crops is one such alternative. They can result in relatively lower greenhouse gas emissions compared to traditional energy sources. Up to now, corn grain is the most researched energy crop. Cellulosic perennial crops such as switchgrass, miscanthus and fast growing trees are also promising energy crops and are expected to help with the energy supply. The 2007 Renewable Fuel Standard requires 16 billion gallons of a total of 36 billion gallons of renewable fuels to be cellulosic biofuels by 2022. Many studies are being done to evaluate costs and feasibility of different potential feedstocks and the …
